When a Perl::Critic::ProfilePrototype is evaluated in string context,
it produces a multi-line summary of the policy name,
default themes,
and default severity for each Perl::Critic::Policy object that was given to the constructor of this ProfilePrototype.
If the Policy supports an additional parameters,
they will also be listed (but commented-out).
The format is suitable for use as a .perlcriticrc file.
